Information returned by a server to a client includes instructions,
executable by either a proxy server or the client, for converting the
returned information from a first representation to a second
representation. The representation conversion may be made by a proxy
server, for example, to make transmission of the returned information to
the client more efficient, and/or to render the returned information in a
format suitable for display by the client. By having the server embed
representation conversion information in the query response, the
representation conversion can take into account the type and other
characteristics of information being returned, as well as the
computational and display characteristics of the client.
